H150-R 13.56MHz RS232 reader with DB9 serial and USB-A cable

H150-R 13.56MHz RS232 MIFARE Desktop Reader with Card Recess, DB9

Q: What is the USB plug on the H150-R cable for?

Power. The H150-R runs on 5 V DC at about 100 mA, which an RS232 port does not provide, so the USB-A plug takes 5 V from a USB port while card data travels on the DB9 connector.

Q: What is the difference between the H150-R and the H110-R?

Both are 13.56MHz RS232 readers with the same card list, 80 mm range and serial settings. The H150-R uses the angled 110 × 80 × 26 mm housing with a card recess and a DB9 + USB-A cable; the H110-R is a 10 mm slim pad.

Q: Can I change the baud rate of the H150-R?

Yes. 9600 bps is the default, and 19,200 or 115,200 bps can be selected. Tell us the rate your host needs and it is confirmed before shipment.

Q: Does the H150-R read NTAG213 tags?

Yes, the UID of NTAG213 and NTAG203 tags, as well as MIFARE Classic 1K and 4K cards. It does not read NDEF records or write to tags.

The H150-R is a read-only 13.56MHz RS232 reader in the angled classic desktop housing with a card recess. It reads MIFARE Classic 1K/4K, NTAG203 and NTAG213 UIDs at up to 80 mm and sends them over a DB9 serial connection at 9600 bps, 8-N-1, with a documented STX/ETX frame for parsing.

Frequency: 13.56 MHz
Cards / tags: MIFARE Classic 1K (S50), MIFARE Classic 4K (S70), NTAG203, NTAG213, other ISO 14443A cards (UID)
Interface: RS232, DB9 connector
Output: 10-digit decimal card UID
Read range: Up to 80 mm (depends on card and environment)

Why integrators choose the H150-R

DB9 and USB-A on one cable — serial data on a DB9 connector, plus a USB-A plug for the reader's 5 V DC supply (100 mA).
9600 bps, 8-N-1 default — 19,200 and 115,200 bps are also selectable for hosts that run faster ports.
Checksum-verified frames — STX (0x02), length, card type, 5-byte serial number, BCC and ETX (0x03), alongside the plain 10-digit decimal default.
Card recess — angled 110 × 80 × 26 mm housing, about 175 g, so the card lies in a fixed position during a transaction.
MIFARE Classic and NTAG213 — UIDs read in under 200 ms at up to 80 mm.

Where the H150-R fits

The H150-R is meant for fixed stations whose software listens on a COM port: self-service kiosks, industrial terminals, legacy attendance and POS PCs, and controllers with a serial input. The application receives each read in the background, so a card is captured even when no window has the focus.

The card recess suits stations where the card stays on the reader while a transaction or registration completes. Its supplied cable ends in a DB9 connector for data and a USB-A plug for power, so a PC with a COM port can supply both without a separate power adapter.

To check a sample before writing any code, open the port in a serial terminal at 9600 bps, switch the view to hex and present a card. With framed output, every read starts with 02 and ends with 03; with plain output you see the 10-digit card number.

Serial frame reference

Besides the default 10-digit decimal card number, the H150-R documents a framed message for software that needs to validate every read:

Field	Content
STX	`0x02`, start of frame
Len	Length byte
Card type	Identifies the card type
Serial number	5 bytes
BCC	Block check character (checksum)
ETX	`0x03`, end of frame

Parse from STX to ETX instead of relying on timing, and discard frames whose BCC does not match. The 125kHz L150-R in the same housing also frames its data between STX (0x02) and ETX (0x03); check its field layout before sharing parser code. Which output your units ship with, plain or framed, is confirmed in the quotation.

Integration in 4 steps

1
Plug the DB9 connector into the host's COM port (or a USB-to-RS232 adapter) and the USB-A plug into a USB port for the 5 V supply.
2
Open the port at 9600 bps, 8 data bits, no parity, 1 stop bit.
3
Present a card in the recess; the LED and buzzer confirm the read and the card data arrives on the port.
4
With framed output, read from STX (0x02) to ETX (0x03), verify the BCC byte, then take the 5-byte serial number.
